This is an offshoot from a thread on SET... feel this is a more appropriate venue. The general question is "how do you size the inductance for loading a triode" The two sides are: The inductance value required depends on the reflected load The inductance value required depends on the source impedance (Triode Rp) I fall into the source Z determining the inductance (and may be the only one) and in order to start things off I'll add a few pictures. The signal being traced starts with a couple of full scale 20hz sines followed by the cannon fires from the 1812 and then closes with a couple of 20hz sines. When looked at as a loadline on some 2A3 curves we get the following. 2A3 is operating at book points with a 25hy inductive load. The green represents a 2K5 reflected load and the blue a 10K reflected load. dave |
